Introduce common variables to define a generic build instruction that is then used in specific board specific description.
Labels are introduced in the evm.rst files to be then reused in variant board documentation as well.
While at this, drop using ARCH=arm when building u-boot sources. This practice has been discouraged for some time and can potentially create problems with Kconfig rules related to aarch64. It's best to avoid this approach.
Signed-off-by: Nishanth Menon nm@ti.com --- Changes since V1 * Updates to fix up typos, ARCH=arm space before \ and misc.
